Нажмите кнопку на странице профиля, чтобы переключить вопрос Django

Кнопка следует за пользователем должным образом, однако, когда кнопка переключается, чтобы отменить подписку, она переключается на все профили пользователей. Не следует за ними все, но кнопка переключается. Мне нужно поменять на JsonResponse / Ajax и вернуть.

ПОЛНЫЙ ПРОЕКТ ЗДЕСЬ: https://github.com/forafekt/save-live-set

Модели: 

from django.db import models
from django.db.models.signals import post_save
from django.dispatch import receiver
# from django.http import request

from config.settings import base

User = base.AUTH_USER_MODEL


class ProfileManager(models.Manager):
    def toggle_follow(self, request_user, username_to_toggle):
        profile_ = Profile.objects.get(user__username__iexact=username_to_toggle)
        user = request_user
        is_following = False
        if user in profile_.followers.all():
            profile_.followers.remove(user)
            print("REMOVE FOLLOW")  # testing
        else:
            profile_.followers.add(user)
            is_following = True
            print("ADD FOLLOW")  # testing
        return profile_, is_following


class Profile(models.Model):
    user = models.OneToOneField(User, on_delete=models.CASCADE)
    followers = models.ManyToManyField(User, related_name="is_following", blank=True)
    activated = models.BooleanField(default=False)

    objects = ProfileManager()

    def __str__(self):
        return str(self.user.username)

    @receiver(post_save, sender=User)
    def make_user_profile(sender, **kwargs):
        if 'created' not in kwargs or not kwargs['created']:
            return

        # Assumes that the `OneToOneField(User)` field in "Profile" is named "user".
        profile = Profile(user=kwargs["instance"])
        # Set anything else you need to in the profile, then...
        profile.save()`
